How to check the optical port on a Huijue switch

You can check the transmit (TX) and receive (RX) optical power of Huawei switch ports using the display transceiver or display interface transceiver verbose commands.Viewing Optical Module InformationTo check the optical module on a specific port:Run the command: display transceiver interface This shows details such as transceiver type, connector type, wavelength, transfer distance, vendor, and serial number .To view all optical ports on the switch: display transceiver This lists the optical module information for every port .Checking TX and RX Optical PowerFor detailed transmit and receive power:Use the verbose option: display transceiver interface verbose or display interface transceiver verbose The output includes:Current RX Power (dBm) – the received optical powerCurrent TX Power (dBm) – the transmitted optical powerTemperature, voltage, and bias current of the moduleHigh and low thresholds for RX and TX power Example output snippet:CodeCopyCurrent RX Power (dBm): -3.07Current TX Power (dBm): -2.64Default RX Power High Threshold (dBm): 2.50Default RX Power Low Threshold (dBm): -12.70Default TX Power High Threshold (dBm): 1.00Default TX Power Low Threshold (dBm): -9.50 Additional TipsEnsure that both local and remote optical modules have the same wavelength to avoid link issues .If optical power is too low or too high, check fiber connections, clean connectors, or replace faulty modules .Prefer Huawei-certified optical modules to prevent compatibility and data bus issues .You can also use display interface to check port link status, traffic statistics, and transceiver working status . By using these commands, you can effectively monitor the optical power and health of your Huawei switch ports, helping to maintain stable network performance.
